The extent of solubility of octanoic acid in 1M HCl, 1M NaOH , or pure water is to be explained and the treatment of morphine with strong acids is to be stated. Concept introduction: Octanoic acid ( C 8 H 16 O 2 ) is a carboxylic acid . Carboxylic acids undergo nucleophilic addition reactions as it contains -OH nucleophile and formed derivatives of acid. As carboxylic acids are weak acids they partially dissociate to form H + and RCOO - ions. Amines react with hydrochloric acid to form soluble compounds. To determine: The extent of solubility of octanoic acid in 1M HCl, 1M NaOH , or pure water and the treatment of morphine with strong acids.

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.

Interpretation Introduction
Interpretation: The extent of solubility of octanoic acid in
1MHCl,1MNaOH, or pure water is to be explained and the treatment of morphine with strong acids is to be stated.
Concept introduction: Octanoic acid
(C8H16O2) is a carboxylic acid. Carboxylic acids undergo nucleophilic addition reactions as it contains
-OH nucleophile and formed derivatives of acid. As carboxylic acids are weak acids they partially dissociate to form
H+ and
RCOO- ions. Amines react with hydrochloric acid to form soluble compounds.
To determine: The extent of solubility of octanoic acid in
1MHCl,1MNaOH, or pure water and the treatment of morphine with strong acids.
Experiment:
Each team will be provided with 5g of a mixture of acetanilide and salicylic acid. You will divide it into three 1.5 g portions in separate 125 mL Erlenmeyer flasks savıng some for melting point analysis. Dissolve the mixture in each flask in ~60mL of DI water by heating to boiling on a hotplate. Take the flasks off the hotplate once you have a clear solution and let them stand on the bench top for 5 mins and then allow them to cool as described below.
Sample A-Let the first sample cool slowly to room temperature by letting it stand on your lab bench, with occasional stirring to promote crystallization.
Sample B-Cool the second sample 1n a tap-water bath to 10-15 °C
Sample C-Cool the third sample in an ice-bath to 0-2 °C
Results:
weight after recrystalization and melting point temp.
A=0.624g,102-115°
B=0.765g, 80-105°
C=1.135g, 77-108
What is the percent yield of A,B, and C.
